got the treo and it needs a bigass box. this is coming off memory from what the treo guy told me. i wrote it down but i left it at my buddies. ill update when i get the exact measurements. but i beleive he said the box had to be 4.2 sq ft. and with a port 40 inches long. thing is i dont want the box to take up the whole trunk i had a cool design planned for the side panels on the left and right of the box. . just wondering if u guys could help me out with designing the box giving me different measurements i can use. i never built a box and this really isnt the best sub to go fuckin around with. ill probably have someone help me out with it. thanks guys again.
